What Have You Done To Your Stagea Lately?

[Daleo]

With the 7psi actuator its hard to run any more than that, even with a controller. You may get 20psi midrange but it will always drop to around 15 by redline without increasing the spring tension on the wastegate.

The exhaust manifold pressure literally blows the wastegate puck open on boost bypassing the turbo hence welding a stiff spring to the actuator to hold it better.

All the stock turbo failures I have seen have been due to oil starvation/heat on the rear bearing as Dale mentioned.

Lol Scotty, I should have referenced you in there mate; it's been your hard work and development that has brought this information to light.

I fitted the dump by itself on a factory exhaust and I'm convinced it makes the turbos life easier.

Speaking of which, Slippy and I were both talking about running a dump on the standard exhaust.

Are there power gains to be seen from running an aftermarket dump on the factory exhaust? Would it be more hassle than it's worth running a custom system from the turbo back to the factory "sports" muffler? I know that the factory exhaust weighs a ton so I figure it's worthwhile getting rid of, but I quite like the fact that I can press a button and my exhaust goes quiet, but if it's going to significantly impact the gains it's just a waste of money trying to keep it..

Yes,, 100% worth the effort.

Did you do it Andy?

If so, what did you run before the muffler? Dump, hi-flow cat, muffler? Or another muffler as well?

[bigkevracer]

Standard dump has a cat in it. Which then connects to a mid pipe... with a cat in it... and the massive box of baffles.

If you really want to keep the Nismo rear I'd do dump and mid pipe. But you should see a huge gain just doing dump and midpipe.

Andrew at AM Performance designed his exhaust so that it matches up to the factory mounting locations, so you can buy a dump and midpipe and it should be easy to connect to the Nismo muffler. Or just get him to do it, either way.

This sounds good.

So would the midpipe replace the baffles? I want to get rid of that. Do you know if his system has a cat too? Think it would be a lot louder replacing the standard dump (cat), midpipe (cat) and box of baffles with just a cat?

If you want it quiet, get a Blitz NUR cat-back and then get whomever to make up a dump and frontpipe/cat to bolt up to the Blitz.

Stock is 82dB

Blitz is 82dB (but 80mm and straight through design. Cheap too)

Everything else is 86db+

Yeah see I'm fine with that every other day of the week, but the little switch is a nice thing to have. Especially while driving interstate to get rid of the drone.

Out of curiosity, what are the Blitz cat backs worth?

[jasevr4]

May/may not have just bought some Bride seat rails. Impulse buy?

Thats what I like about the switch as well

I would be interested in your current system if you upgrade.

[Commsman]

I got mine thru Jesse a while back & it cost ~$950. People have reported them for as low as $799 from Just Jap (plus freight?), depending on exchange rates & how many they bring in at a time.

Point to note, exhausts get louder over time as the sound deadening settles down. I'm very pleased I didn't go with a louder one as mine is now probably at the level that most guys would say is what they like, but if it keeps getting louder so help me..... lol.

Also, the tip is a bit on the big side for a 'mature' bloke like me.

[Fgjoh]

so far tis week i have made a radiator air guide and just started on my corner sub box robably some amp racks later in the week

[jidge]

Hey BigKev, Do you know how many db yours is?

[Jetwreck]

Another late one trying to resolve the timing/electrical issue.

I'll attack this again tomorrow night....thanks iain for your help.

Here's hoping you get it sorted mate; how many ladders have you walked under?

[PN-Mad]

Front trim off and ECU out, to take down to SAS to see if they can chip it for tuning the Turbo Kit!

Fingers Crossed!

[zei20l]

no worries craig, see you there again tonight!

when we were bleeding the attesa system last night, craig put his foot on the brake and one of my braided brake lines split and pissed out brake fluid.

LUCKILY the old set were still next door. threw them on and im able to drive

just be aware M35 drivers, dont get the cheaper braided brake lines from IM. just get nismo or have a set made up by maltech. actually wasnt someone organising that?? im pretty sure i gave a set to someone to have that done

Can you ask them for Craig and my ECU back that we gave them 18 months ago to see if they can tune our cars.

Faaark! You surely dodged a bullet there Iain; could've been a disaster.

Specialised Brake & Clutch in Penrith made me a set of Goodridge ADR legal lines for my last car; they were around $80-$90 each. All pressure tested to ensure things like that don't happen.
